Table 4. Variance estimates from a mixed model of proportion of eggs normally fertilized across different sperm concentration in mussels, fitted using a Bayesian approach. Shown are posterior modes and the 95% highest posterior density (HPD) intervals for random effects of measurement block (V block), male identity (V male), female identity (V female), specific combinations of males and females (V male × female), and specific environment (Ve ; residual variance).V male, V female, andV male × female were fitted heterogeneously for each sperm concentration.
